Thereís nothing wrong for wanting an indicator. I did when I first got my TnT kit. After using it for a few hours, I never looked at it, ever.
To the OP, I think this is why you are getting the responses you are. Iím in the same boat. Got one, donít use it. Havenít looked back.
BTW, my indicators are RV bubble levels stuck on the tractor and the QH.
